Role: Agentic AI Engineer

Location: Rochester, MN (Remote)

Responsibilities: Design, build, and productionize ML models for personalization, forecasting, anomaly detection, and NLP on GCP (Vertex AI, BigQuery ML, Dataflow). Develop scalable data and feature pipelines; implement feature stores (Feast) and streaming ingestion (Pub/Sub, Kafka) for real-time inference. Implement agentic AI patterns: multi-agent orchestration, tool-use, retrieval-augmented generation (RAG), and function calling with guardrails (policy/PII filters). Optimize online inference for latency and cost using Vertex AI Endpoints, GPU/TPU where applicable, and autoscaling on GKE. Establish experiment frameworks (A/B, interleaving, bandits) and offline evaluation (precision/recall, ROC-AUC, NDCG, MAP). Integrate vector search (Vertex Matching Engine / FAISS / Elasticsearch) for semantic retrieval and recommendations. Ensure privacy, security, and compliance (GDPR/CCPA); apply differential privacy where needed and follow model governance practices. Document designs, review code, and collaborate with product, data engineering, and platform teams. Desired Technical Skills Languages:

Python (primary), Java/Scala (nice to have).

Frameworks:

TensorFlow, PyTorch, scikit-learn; JAX optional.

Pipelines & Features:

Apache Beam/Dataflow, Airflow/Cloud Composer, Feast.

RAG & Agents: LangChain/LlamaIndex, function calling, toolformer patterns, vector DBs (FAISS, Chroma, Elasticsearch).

Data & Streaming:

BigQuery, Spark, Kafka, Pub/Sub.

Serving:

Vertex AI Endpoints, KFServing, Triton; Docker, Kubernetes (GKE).

Observability:

MLflow, Vertex Experiments/Model Registry, Prometheus, Grafana.

Cloud:

GCP (Vertex AI, BigQuery, GCS) primary; familiarity with AWS (SageMaker) and Azure ML.

Preferred Experience & Capabilities Delivered ML systems at scale (batch + real-time) with measurable business impact. Hands-on with vector search, RAG, and agentic workflows using tools/actions and governance (safety filters, jailbreak protection). Expertise in feature engineering, data quality, and drift detection (data/model). Strong understanding of IR/ranking metrics and online experimentation. Ability to mentor, perform code reviews, and contribute to architectural decisions. Excellent communication with cross-functional stakeholders. Note:

Primary development environment is GCP (Google Cloud Platform). Flexibility to work with AWS and Azure is desired for portability and interoperability. Skills
